摘要/Abstract

摘要： 运用最小二乘法建立了某型涡扇发动机的动态数学模型,并利用相似原理把它推广到全飞行包线范围。动态数学模型在仿真计算机上运行,通过输入输出接口与控制器、执行机构实物进行连接,组成基于VX I总线技术的涡扇发动机控制系统半实物仿真系统。对涡扇发动机实际工作过程的半实物仿真结果表明,系统能实时地反映在控制系统作用下发动机的运行情况,为发动机全权限数字电子控制(FADEC)系统研究提供了良好的试验手段。

Abstract: Least square method was brought to use in establishing a dynamic model of a turbofan aeroengine,and similarity theory was introduced to extend the model to the full envelop region.The dynamic model was run on a computer.Meanwhile,through the input and output interfaces,the computer was connected with a real control system.Then based on VXI technology,hardware-in-the-loop simulation system of a turbofan aeroengine control system was conducted.The simulation test at dynamic conditions was completed and the results of simulation show that the system not only can control engine completely,but also provides a convenient means for FADEC system research.

Key words: Turbofan engine;Control system;Semi physical simulation;Least square method;Dynamic mathematical model
